Moses,
Thanks. That's good advice. The VSS is interesting to me. I found that if I was able to get up to around 50mph (down hill) it would upshift to high gear (OD?) and I could cruise at 60 to 70 no problem-so it seemed that vehicle speed was somehow related to shift problem. I drove from SF bay to North Tahoe. Going up hill if I had to downshift manually when I went back to OD the upshifts happened as long as speed was sufficient. The really odd thing that happened when I got off the freeway was that it didn't want to come out of gear when I approached a stop. Luggin motor as if it was a manual tranny in high gear. I popped in neutral to keep it running. Then it was back to the same trouble when I got going again-no up ( or very delayed)shift in mid gear unless I could get up to speed.
I was hoping to drive it back home to go to my tranny shop that did the seals and filter. That sounds ill advised. I could tow home or find a local shop to check it out. Do you know anyone in North Tahoe/Truckee area? I could take a look underneath if I knew what to look for.
Thanks again, Fred
